The Hollyland LARK C1 DUO for iOS is a pocket-sized two-person wireless microphone system that plugs straight into an iPhone or iPad with a Lightning port. It suits content creators, vloggers, mobile journalists, interviewers and small businesses recording talking-head video, podcasts or live streams on a phone. The kit has two clip-on transmitters with built-in omnidirectional electret microphones and one dual-channel receiver that plugs into the Lightning port and is powered by the phone. It runs on 2.4 GHz with a range of up to 200 m line-of-sight (about 40 m through obstacles). Each transmitter runs for about 8 hours, and the charging case can recharge both transmitters up to three times on the go, for up to 32 hours in total. Switchable noise cancellation reduces background noise, and the LarkSound app shows battery level and adjusts volume. Transmitters weigh just 11.5 g. In the box: charging case, two transmitters, receiver, USB-A to USB-C cable, two furry windshields and documentation.
